Last year, in celebration of National Park Week, Chimani Apps gave away their suite of National Park apps. Normally, the apps sell for between $4.99-$9.99 each with an average rating of 4 1/2 stars, but the company gave away one million downloads. Now, Chimani is back with five new national park apps that feature an augmented reality viewer, crowd-sourced maps and a social sharing tool enabled with Near Field Communications (NFC) technology. Better yet, they are all free.

“Chimani users are now able to actively contribute to the national park community and help build better geo-spatial data for each of the parks,” said Kerry Gallivan CEO/Co-Founder in a NationalParksOnline article.

The company is releasing a new app on each of the five days of National Park Week. New parks added are Grand Teton National Park, Glacier National Park, Olympic National Park, Sequoia and Kings Canyon National Parks and Bryce Canyon National Park. These, and all other Chimani apps, will be available for free starting Monday, April 22.

The apps have constantly updated maps, event schedules, points of interest, hiking details, as well as sunset and sunrise times for scenic overlooks. Users can access tide schedules along the coast, review lodging options and more on the apps, all designed to work without a cellphone signal.

We like that Chimani does not just throw their apps out there and hope for the best. Their users actively contribute to the national park community by helping build better geo-spatial data for each of the parks.

“A great example of this is Openstreetmaps.org’s user Tomthepom who spent the winter meticulously editing the park data within Grand Canyon. Thanks to Tom, the data found within the Chimani maps is the most detailed and up-to-date available anywhere – digital or print,” said Gallivan.

The Chimani apps are available for the iPhone, iPad, Amazon Kindle and Android devices. They can be downloaded directly from Apple’s iTunes App Store, Google Play and Amazon AppStore.
